the volume of a rectangular prism is 10 cubic feet. what could the dimensions of the prism be
Answers
Answer: 2x5x1, 1x10x1 (in any order) and any 3 multiples that make 10
Step-by-step explanation:
Answer:
There are multiple possible sets of dimensions for a rectangular prism with a volume of 10 cubic feet. Here are some possible solutions:
A rectangular prism with dimensions of 1 ft x 2 ft x 5 ft (length x width x height) would have a volume of 10 cubic feet, since 1 x 2 x 5 = 10.
A rectangular prism with dimensions of 2 ft x 1 ft x 5 ft (length x width x height) would also have a volume of 10 cubic feet, since 2 x 1 x 5 = 10.
A rectangular prism with dimensions of 0.5 ft x 1 ft x 20 ft (length x width x height) would also have a volume of 10 cubic feet, since 0.5 x 1 x 20 = 10.
A rectangular prism with dimensions of 5 ft x 1 ft x 2 ft (length x width x height) would have a volume of 10 cubic feet, since 5 x 1 x 2 = 10.
There are infinitely many other possible sets of dimensions for a rectangular prism with a volume of 10 cubic feet.

w-ul = (Type an exact answer, using radicals as needed.)
Answers
The value of ||w - u || = 3 sqrt 2
How to solveGiven:
u = 2i - 3j
w = - i - 6j
w - u = ( - i - 2i ) + ( - 6j - (-3j))
w - u = - 3i - 3j
|| w - u || = sqrt [ - 3^2 + - 3^2 ]
||w - u || = 3 sqrt 2
The concept of a radical in mathematics refers to the symbolic representation (√) of finding the roots of an expression or a number.
The widely known and frequently used kind is the square root (√), which reveals a positive value that, when multiplied by itself at once, generates the radicand.
Other forms may include cube roots (∛) or fourth roots (∜). To simplify radicals, one can factor out those factors within it that result in perfect cubes or squares from their corresponding radicands.

Translate 2 3 y − 9 < y + 1 into a sentence. Nine than two-thirds of number is less than the number .
Answers
The sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."
To translate the inequality expression "2/3y - 9 < y + 1" into a sentence, we can break it down into smaller parts:
"2/3y" represents two-thirds of a number.
"9" represents the number nine.
"y + 1" represents the number increased by one.
Now let's construct the sentence:
"Nine less than two-thirds of a number" - This refers to the expression "2/3y - 9," indicating that we have subtracted nine from two-thirds of a number.
"is less than" - This is the comparison symbol in the inequality.
"the number" - This refers to the expression "y + 1," representing the number increased by one.
Combining these parts, we form the sentence: "Nine less than two-thirds of a number is less than the number."
Hence, the correct sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."

Explanation: In the y = mx + b (or y = mx + c) format, the m is the slope of the line and the c/b is the y-intercept, or where the line crosses the y-axis. If we substitute the information from the given equation, y = 2x + 1, into the general formula, we know that the m is 2 and c is 1.

b. Which function has the greatest growth factor? Justify your response.
Answers
Answer:
A)
Function A: Exponential
Function B: Linear
Function C: Exponential
Function D: Exponential
B) Function A
Step-by-step explanation:
Function A: This is exponential because- (1, 3)(2,9)(3,27)
It is not going up by the same number each time. However, it is multiplying by 3 each time which means it is exponential.
Function B: This is linear because- (1, 64)(1, 80)(1, 96)
It is going up by 16 each time, (a constant number) which means it is linear.
Function C: This is exponential because- there is a curve, linear is always a straight line. But, this has a curve which means it is exponential.
Function D: This is exponential because- It is increasing by a percentage and not a constant number. It is increasing by 1% which means it is exponential.
The function that has the greatest growth factor is Function A because, Function A multiplies by 3 each time. Function B is linear, exponential functions always pass linear functions despite how "steep" they are. Eventually, the exponential function will surpass it. Function C is also exponential but is not as "steep" as Function A. Function A multiplies by 3 each time but Function C increases less. Function D is also exponential, and for the same reasons as Function C, Function A has the greatest growth factor.

By law, an industrial plant can discharge not more than 500 gallons of waste water per hour, on the average, into a neighboring lake. Based on other infractions they have noticed, an environmental action group believes this limit is being exceeded. Monitoring the plant is expensive, and only a small sample is possible. Four one-hour periods are selected randomly over a period of one week. The following are observed:
1384, 683, 1534, 405
Do you reject the null hypothesis that the limit is not being exceeded?
Answers
Answer:
We conclude that not more than 500 gallons of wastewater per hour, on average, is discharged into a neighboring lake.
Step-by-step explanation:
We are given that an industrial plant can discharge not more than 500 gallons of wastewater per hour, on average, into a neighboring lake.
Four one-hour periods are selected randomly over a period of one week. The following are observed:
1384, 683, 1534, 405
Let \(\mu\) = population average gallons of wastewater discharged per hour
So, Null Hypothesis, \(H_0\) : \(\mu \leq\) 500 gallons {means that not more than 500 gallons of wastewater per hour, on the average, is discharged into a neighboring lake}
Alternate Hypothesis, \(H_A\) : \(\mu\) > 500 gallons {means that more than 500 gallons of wastewater per hour, on the average, is discharged into a neighboring lake}
The test statistics that will be used here is One-sample t-test statistics because we don't know about population standard deviation;
T.S. = \(\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }\) ~ \(t_n_-_1\)
where, \(\bar X\) = sample mean = \(\frac{\sum X}{n}\) = 1001.5 gallons
s = sample standard deviation = \(\sqrt{\frac{\sum (X - \bar X)^{2} }{n-1} }\) = 543.79
n = sample of periods = 4
So, the test statistics = \(\frac{1001.5-500}{\frac{543.79}{\sqrt{4} } }\) ~ \(t_3\)
= 1.844
The value of t-test statistics is 1.844.
Since in the question we are not given with the level of significance so we assume it to be 5%. Now, at 0.05 level of significance, the t table gives a critical value of 2.353 at 3 degrees of freedom for the right-tailed test.
Since the value of our test statistics is less than the critical value of z as 1.844 < 2.353, so we have insufficient evidence to reject our null hypothesis as it will fall in the rejection region.
Therefore, we conclude that not more than 500 gallons of wastewater per hour, on average, is discharged into a neighboring lake.

an = -1 + 4( n - 1)
an = -1 + (-4)( n - 1)
an = 4 + (-1)( n - 1)
an = -4 + (-1)( n - 1)

Answer: The correct formula for the sequence -1, -5, -9, ... is an = -4 + (-1) n - 1). This formula uses the common difference of -4 and the first term of -1 to calculate the value of the nth term in the sequence.

5cm
Write down your answer and show how you worked out your answer.
Answers
Answer:
a = 9 cm
Step-by-step explanation:
We are given that
perimeter of shaded area = 1 m = 100 cm
But according to given diagram
The perimeter of shaded area = ( 3a + 2a + 2 + 2a + 3 + 2 + 3a + 3 ) cm
= (10a + 10) cm
By using given perimeter = 1 cm we get
The perimeter of shaded area = ( 10a + 10 ) cm = 100 cm
10a = 90 cm
a = 90 / 10 = 9 cm
Thus
a = 9 cm

a circle with area 36pi has a sector with a central angle of 48°. what is the area of the sector?
Answers
Answer:4.8π
Step-by-step explanation:
Φ=48°
Area of circle=36π
Area of circle=π x r^2
36π=πr^2
Dividing both sides by π we get
r^2=36π/π
r^2=36
Take them square root of both sides
√(r^2)=√(36)
r=6
Area of sector=Φ/360 x π x r x r
Area of sector=48/360 x π x 6 x 6
Area of sector=(48xπx6x6)/360
Area of sector=1728π/360
Area of sector=4.8π

A farmer is building a fence to enclose a rectangular area consisting of two separate regions.

Answers
Let the width be x and the length be y as shown in the figure.
The perimeter of the fence is 246 feet so it follows:
\(\begin{gathered} 3x+2y=246 \\ y=\frac{246-3x}{2} \end{gathered}\)The area of the fence is given by:
\(\begin{gathered} A=xy \\ A=x(\frac{246-3x}{2}) \\ A=123x-\frac{3}{2}x^2 \end{gathered}\)Differentiate w. r. t. x to get:
\(\frac{dA}{dx}=123-3x\)For maxima and minima calculation, the derivative is zero so it follows:
\(\begin{gathered} 123-3x=0 \\ 3x=123 \\ x=\frac{123}{3}=41 \end{gathered}\)So the width is 41 feet and the length y is given by:
\(y=\frac{246-3(41)}{2}=\frac{123}{2}=61.5\)So the width is 41 feet and length is 61.5 feet, the area covered is 2521`.5 sq feet.
